The "Sake Set" consists of a slender, cylindrical "sake pourer" and a set of two "guinomi" (sake cups). It pairs perfectly with well-chilled Japanese sake. It's an ideal gift for Father's Day or for men who enjoy alcohol. 【About the Brand】 Matsutoku Glass Co., Ltd. began in 1922 (Taisho 11) as Marusa Valve Manufacturing in Nakano-go, Honjo-ku, Tokyo, primarily manufacturing glass for light bulbs. Later, it relocated to its current location (Kinshi, Sumida-ku, Tokyo) and began manufacturing glassware and craft glass. In 1958, the company changed its name to "Matsutoku Glass Co., Ltd." and, utilizing the know-how gained from manufacturing glass for light bulbs, released the ultra-thin glass "Ushihari Glass" with a thickness of 0.9mm. In 2003, it received the Accent on Design Best Product Award at the New York Gift Fair, earning high praise both domestically and internationally. In 2005, it announced "e-glass," recycled glass that completely harmlessly processes waste fluorescent tubes, and won the Grand Prize and Governor of Tokyo Award at the 1st Traditional Crafts Challenge Award. In 2006, it was certified as the first eco-mark product in Japan for glassware. Furthermore, Matsutoku Glass products are designated as "Edo Glass," a traditional craft of Tokyo. "Precautions for Using Matsutoku Glass Products" ・Wash with a neutral detergent before first use. Also, wash in the same way after use. Using abrasive sponges, metal scrubbers, or cleansers that may scratch the glass can cause breakage. ・When washing the inside of the glass, please be very careful. Washing with force from the inside by twisting can cause breakage and unexpected injury. We recommend using a sponge with a handle. ・Sudden temperature changes (especially rapid cooling) can cause breakage. Do not put cold items into the glass while it is hot, or place it on a wet surface. ・Scratches on the glass make it more prone to breakage. Handle the glass carefully to avoid bumping it against other glass or hard objects. ・Stacking glasses can cause breakage or make them impossible to separate. Do not stack glasses unless they are specifically designed for stacking. ・This is not heat-resistant glass or tempered glass. Please use with care.
